摘要:我们开发了一种在无金属条件下可循环利用的高价碘介导的β-酮酸酯和β-二酮的直接脱氢α,β'-双官能化方法,为合成苯并稠合的2,3-二氢呋喃提供了直接的方法.这种有效,温和的方法具有广泛的底物范围和非常好的官能团耐受性,可用于天然酚醛糖苷的受保护糖苷配基的多步合成.提出了一种涉及将迈克尔加成至烯酮中间体并随后进行氧化环化的机理.

标题 :Enzymatic synthesis of kavalactones and flavokavains
发明人:PLUSKAL TOMÃ?S; Weng jing-ke
权利人:WHITEHEAD INST BIOMEDICAL RES
摘要:Disclosed are methods, compositions, proteins, nucleic acids, cells, vectors, compounds, reagents, and systems for the preparation of kavalactones, flavokavains, and kavalactone and flavokavain biosynthetic intermediates using enzymes expressed in heterologous host cells, such as microorganisms or plants, or using in vitro enzymatic reactions. This invention also provides for the expression of the enzymes by recombinant cell lines and vectors. Furthermore, the enzymes can be components of constructs such as fusion proteins. The kavalactones produced can be utilized to treat anxiety disorder, insomnia, and other psychological and neurological disorders. The flavokavains produced can be utilized to treat various cancers including colon, bladder, and breast cancers.
